Amazon intros Kindle software for Mac

Amazon has introduced the Mac version of its Kindle software today, expanding the platforms on which it is available to include PCs, Macs, the Kindle device, iPhones and BlackBerrys.

The software is available for free via Amazon, and lets users purchase and read e-books on their computers. Amazon offers 450,000 titles via the Kindle Store.

Additionally, Amazon said an iPad Kindle app would be available in April.

Despite selling a standalone e-reader device, Amazon says e-book sales are much more profitable, so Kindle sales are not top priority. However, Amazon remains the market leader for e-book sales and e-readers.
